Abstract

The system has a ground`s electric impedance measurement device with conductor elements placed on the outer side of a tire (6) of one of wheels (5) of a vehicle and in contact with the ground during a portion of revolution of the wheel. The device permits the measurement of electric impedance between the elements, when they are in contact with the ground. A measurement unit permits the determination of electric impedance of the ground by application of Ohm`s law. A data processing device is connected to the measurement unit and permits storage of determined impedance values.
